Seed Germination
7-14 daysSeeds germinate in cool to warm soil; seedlings emerge with fine cotyledons
Scarify seeds or soak 24 hours to improve germination rate; maintain consistent moisture until sprouting; germinates best in temperatures 60-75°F
Seedling & Establishment
3-4 weeksYoung plants develop feathery bipinnate leaves characteristic of the species
Keep soil moderately moist; protect from competitive weeds; thin seedlings to proper spacing; begin hardening off if growing indoors
Vegetative Growth
4-6 weeksPlant establishes deep root system and expands foliage; fern-like leaves become more prominent
Reduce watering frequency as plant matures; apply light mulch to conserve moisture and suppress weeds; minimal fertilizer required; deep roots develop
Flowering
6-8 weeks (summer through early fall)Distinctive round pink and white flower clusters appear at branch tips; flowers attract butterflies and bees
Deadhead spent flowers to encourage continued blooming; flowers provide excellent nectar source; enjoy as cut flowers; allow some flowers to set seed for self-propagation
Seed Production & Dormancy
8+ weeks through winterFlowers develop into small linear seed pods; foliage may decline in fall; plant enters winter dormancy
Leave seed pods on plant for self-seeding and wildlife food; no winter protection needed in hardy zones; established plants are extremely hardy; can cut back old growth in early spring
